If and when the world does start to return to something resembling 'normal', chances are it is going to look very different to the one we've just left. No longer will it be acceptable for trains and buses to resemble the mosh pit of a Pantera gig, with people eager to maintain a safe distance from each other. Furthermore, the road network is unlikely to cope with a surge of new drivers on the morning commute. Some of us are going to have to find a new way to get to work.
